Until last year, James Hansen ran the Goddard Institute for Space Studies at NASA. In that role, he issued some of the earliest warnings about the risks of climate change.
Hansen was in Eugene this past weekend to give a keynote speech at the Environmental Law Conference. Before the speech, Hansen sat down with EarthFix reporter Cassandra Profita to talk about his new life as a public speaker and climate scientist at Columbia University.
